Short-wavelength infrared SWIR, IR-B DIN: 1.4–3 μm 100–214 THz 413–886 meV 2,070–966 K (1,797–693 °C) Water absorption increases significantly at 1,450 nm. The 1,530 to 1,560 nm range is the dominant spectral region for long-distance telecommunications (see transmission windows). Mid-wavelength infrared MWIR, IR-C DIN; MidIR. [22]
An infrared heater or heat lamp is a heating ... One classification of infrared heaters is by the wavelength bands ... In the mid 1950s the motor vehicle industry ...
The wavelength range from approximately 200 μm up to a few mm is often referred to as Submillimetre astronomy, reserving far infrared for wavelengths below 200 μm. Mid-infrared , from 30 THz to 120 THz (10–2.5 μm).
Infrared light can be broken up into three categories: near, mid, and far infrared, each offering different wavelengths and energies that may benefit the body in various ways. What is an infrared ...
Infrared radiation is divided into spectral subregions. While different subdivision schemes exist, [46] [47] the spectrum is commonly divided as near-infrared (0.75–1.4 μm), short-wavelength infrared (1.4–3 μm), mid-wavelength infrared (3–8 μm), long-wavelength infrared (8–15 μm) and far infrared (15–1000 μm).

Rotational transitions are responsible for absorption in the microwave and far-infrared, vibrational transitions in the mid-infrared and near-infrared. Vibrational bands have rotational fine structure. Electronic transitions occur in the vacuum ultraviolet regions. Its weak absorption in the visible spectrum results in the pale blue color of water.
While the propagation of electromagnetic waves of all wavelengths is often referred as "radiation", thermal radiation is often constrained to the visible and infrared regions. For engineering purposes, it may be stated that thermal radiation is a form of electromagnetic radiation which varies on the nature of a surface and its temperature.
This means when you step into an infrared sauna, you likely won’t get blasted by inferno-level heat. Infrared saunas operate at about 104 to 140 degrees Fahrenheit—significantly lower than ...
